The X-ray emission from neutron stars and white dwarfs has been a subject of extensive research, unveiling unique insights into the high-energy phenomena occurring within these compact stellar remnants. It offers invaluable insights into compact object formation, stellar evolution, and the interplay between magnetic fields, radiation, and matter in extreme conditions. In this meeting, experts from various disciplines will delve into the latest advancements in understanding the X-ray emission processes, its origin, and the astrophysical implications associated with neutron stars and white dwarfs.

This workshop will explore the diverse X-ray emission mechanisms, ranging from thermal emission due to accretion processes, magnetic fields, and nuclear reactions, to non-thermal emission originating from particle acceleration and magnetic reconnection events. X-ray spectra and timing properties will be discussed in detail, enabling a deeper understanding of the underlying emission mechanisms and the associated astrophysical phenomena. The role of X-ray emission in the context of binary systems will be discussed, investigating the interactions between compact objects and their stellar companions.
